Abstract: Surgical constructs, assemblies, kits and methods of tissue fixation are disclosed. A suture passing instrument includes a curved tip integral with a distal end of a shaft, a hand assembly mounted on a proximal end of the shaft, and a flexible strand attached to one or two needles and loaded through a cannulation of the shaft. The curve-shaped tip is adapted to engage dural tissue during repairs of the dura mater. The suture passing instrument can grasp and manipulate dura mater and can allow multiple suture passes through the dura mater without removal of the instrument from the durotomy site. The suture passing instrument is provided with a safety mechanism that prohibits the needle(s) to be fired into nerves, providing a safe, reliable, inexpensive, and speedy repair of a durotomy.

Abstract: A modular access medical system configured to enable a surgeon to conduct a medical procedure in fluid contained within a defined space is disclosed. As such, the system increases visibility to an operating surgeon by eliminating smoke and other vapors formed during use of a medical instrument at the surgical site. The modular access medical system may be formed from a distal end of a cannula configured to be placed into contact with tissue such that fluid can be administered within the cannula and retained therein to facilitate a surgical procedure to be conducted via one or more instruments extending through fluid contained within the cannula.

Abstract: A simple and flexible non-synthetic ligament which easily conforms to a patient's anatomy and can be used independently or in combination with an intervertebral graft, implant or prosthesis. A single length of allograft or autograft is provided, per each side of the vertebral column, to replace and recreate the spinal ligament spanning adjacent vertebrae. The single length allograft or autograft is secured to spine pedicles with fixation devices such as bone screws like interference screws and/or anchors such as SwiveLock® or PushLock® anchors.
